Notes:
1.
All connections/sources must be power-limited and supervised.
2.
12 - 22 AWG (0.33 - 3.31 mm2) wire for 24 VDC circuit is
acceptable.
3.
Power wire distance limitation is set by 1.2 volt maximum line drop
from source to end of circuit.
4.
Maximum distance from FACP to last COMM-BUS device must
not exceed 6,000 feet (1,800 m). Refer to the Wiring Distance Table
in the appropriate FACP manual for wire gauge and distance
limitations.

Setting the DIP Switches
Address Setting
Each ANN-BUS device requires a unique address. DIP switches 1-4 on
S1 are used to set the address. This address will be displayed on the
LCD display as the Station ID number.
A maximum of 8 devices can be connected to the FACP COMM-BUS
communication circuit. COMM-BUS device addresses do not need to be
sequential and can be set to any number between 01 and 08. Note that 00
is not a valid address. The following illustrates the DIP switch settings
for each address (ID Number).
ID Number

Communication Protocol
DIP switch 5 is used to determine the communication protocol of the
315-080. Set DIP switch 5 to ON for COMM-BUS protocol. This switch
must stay in the ON position for proper functionality.

Ensure switch 5 is ON
End-of-Line Resistor
The end-of-line termination resistor must be enabled at S1 on the last
device on the communication circuit. All other annunciators should have
these switches set to disable.
